Member Function Documentation

Transformation2D IMP::algebra::Transformation2D::get_inverse ( ) const

Return the inverse transformation.

const Rotation2D IMP::algebra::Transformation2D::get_rotation ( ) const

Return the rotation.

Definition at line 93 of file Transformation2D.h.

Vector2D IMP::algebra::Transformation2D::get_transformed ( const Vector2D o) const

Perform the transformation on a 2D vector.

Parameters
[in]ovector where the transformation is applied
Note
: The transformation is done first applying the rotation and then the translation

Definition at line 52 of file Transformation2D.h.

const Vector2D IMP::algebra::Transformation2D::get_translation ( ) const

Return the translation.

Definition at line 98 of file Transformation2D.h.

Vector2D IMP::algebra::Transformation2D::operator* ( const Vector2D v) const

Perform the transformation on a 2D vector.

Note
: The transformation is done first applying the rotation and then the translation

Definition at line 61 of file Transformation2D.h.

Transformation2D IMP::algebra::Transformation2D::operator* ( const Transformation2D tr) const

Compose two transformations.

Note
The transformations are composed such that for any vector v (rt1*rt2)*v = rt1*(rt2*v)

+ Here is the call graph for this function:

Transformation2D IMP::algebra::Transformation2D::operator/ ( const Transformation2D b) const

Compute the transformation d which, when composed with b, gives this one.

That is a(x)== d(b(x)) for all x.
